UCHAR.H(3HEAD) Headers UCHAR.H(3HEAD)

uchar.h
unicode utilities header

#include <uchar.h>

The <uchar.h> header provides support for the C11 Unicode utilities. The types and functions provide means for working with data encoded as UTF-16 and UTF-32. When working in non-Unicode locales, these types may not represent Unicode code points.

The <uchar.h> header defines the following types:

char16_t
An unsigned integer that can represent 16-bit characters, generally a single single UTF-16 code unit. A Unicode code point may be one or two UTF-16 code units due to surrogate pairs.
char32_t
An unsigned integer that can represent 32-bit characters, generally a single UTF-32 code unit.
size_t
An unsigned integer that represents the size of various objects. This can hold the result of the sizeof operator. See also stddef.h(3HEAD).
mbstate_t
An object that holds the state for converting between character sequences and wide characters (wchar_t, char16_t, char32_t). See also, wchar.h(3HEAD).
The <uchar.h> header also defines the following functions which are used to convert between char16_t and char32_t sequences and other character sequences:
c16rtomb(3C)
Convert char16_t sequences to multi-byte character sequences.
c32rtomb(3C)
Convert char32_t sequences to multi-byte character sequences.
mbrtoc16(3C)
Convert multi-byte character sequences to char16_t sequences.
mbrtoc32(3C)
Convert multi-byte character sequences to char32_t sequences.
